UNITED STATES PATENT OFFICE 2,029,259 CLOSURE FOR CONTAINERS 'Bollin L. Drake, Port Arthur, Tex., assignor to The Texas Company, New York, N. Y., a corporation of Delaware Applioationhugust 19, 1931, Serial No. 558,023

4 Claims (01. 113-121) vide sealing and closure means which will be T simple, efficient and inexpensive. The invention contemplates a method of crimping into a body member having, an opening formed therein, a neck which may be used in conjunction with a spout, cap or plug.- f,

The invention will be better understood'in connection with the accompanying drawing wherein:v Figure 1 is a sectional elevation'showing abody member and a closure element, and a preferred form of apparatus for carrying out the object of my invention, f

Figure 2 is'an enlarged viewof the body mem-- ber and the closure element before crimping.

Figure 3 illustrates the operation of crimping 20 the body member and the closure element to gether to form a seam. 1

Figure 4 shows a body member with closure ele ment complete, comprising a screw neck adapted to serve as an outlet'for a container acap or 35 plug therefor, and a metal seal adapted to be pressed into the opening in the container after the flange-l2 As shown in Figure 2, the neck I3 is preferably preformed and threaded to receive a spout, cap or plug, as may be desired.

40 In carrying out my invention 1 have provided a movable punch Hand a die l6 adapted to have a relative telescopic movement in order to-engage the upturned flanges 12v and I4 to bend them outwardly and to then flatten the juxtaposed flanges 45 to firmly secure the neck I3 to the body member Ill. The punch l5 and die l6 are mounted in a press of suitable construction which I have illustrated as comprising a base member I! to which the die It is attached by means of a suitable 50 screw I8, and a vertically movable plunger I!) at the lower end ofwhich is formed the punch IS. The punch 15 is provided with a rounded portion lid and a plurality of small projections lib, the purpose of which will be brought out 55 hereinafter. A cylindrical sleeve is mounted -sion spring 2|.

within the base member I! and die It and is pressed upwardly by means of a suitable compres- A second sleeve 22 secured to a rod.23 through a pin 24 movable within a slot 24a is mounted to have sliding engagement with 5 the punch l5 and is pressed downwardly by means of a compression spring 25.

Inassembling the various parts, the body' member In is placed upon the die 16 with the flange l2 surrounding the upper end of the sleeve 0 20. The neck-l3 is then placed upon the body member ill with the flange i4 surrounding the flange l2 as shown more clearly on Figure 2. The punch i5 is then moved downwardly and the rounded portion i511 engages the inner flange I2 '15 and bends the two flanges outwardly. Continued downward movement of the die causes the flanges f I! and M to be flattened as shown in Figure 3 and a tight seam is thusproduced'bymeans of which the neck I3 is securely attached to the. 20

body member Ill. The spring pressed sleeve 22 engages the'upper rim or edge of the neck l3 and holds it in position during the crimping operation. The sleeve 20 serves to position the body member 10 and, of course, slides freely down- 25 ward upon being engaged by the punch l5.

In order to prevent possible relative movement between the neck l3 and the body member ill the projections I5b are provided and extend downwardly at spaced intervals about the lower edge of the punch IS. The projections l5b serve to indent the seam produced by bending outwardly the flanges l2 and I4 and thus prevent any relative rotational movement between the neck l3 and member ID.

It has been found that the closure described herein is very eiiicient, however, if desired a suitable sealing composition may be employed to make the container leak tight. Thus, sealing material may be inserted underneath the an- 40 nularly bent peripheral flange H, for example,

prior to the crimping operation. In the case of containers intended for volatile or inflammable fluids, such as petroleum oils, particularly the lighter products thereof, it is generally desirable to use asealing material.

Referring to Figure 4, it is contemplated that the screw neck 13, which may serve as an outlet or pouring spout for a container the top of which may be the body member ID, may be used in connection with a metal plug or cap 26 and a metal seal 21, adapted to be pressed into the opening in the container top after filling. The cap 26 is formed with a recess at 28 in which a washer 29 of suitable resilient packing such as cork is inserted to make a leak-tight joint between the cap 26 and the neck I3. The metal seal 21 may be pressed tight in the opening by hand after filling. A small amount of sealing compound may be employed if desired.

Obviously many modifications of my invention may be made without departing from the spirit and scope thereof, and I therefore intend no limitation except as imposed by the appended claims.

I claim:

1. The method of attaching a closure element to a container which comprises, providing a body member having an opening therein and an upwardly extending annular flange about the periphery of said opening, providing a neck which may serve as a pouring outlet for the container and having adjacent its lower end an inwardly extending radial flange, said flange being turned upwardly at its inner edge, positioning the neck over the opening in the body member so that the upwardly extending flange of the neck surrounds and rests against the upwardly extending flange of the body member, exerting pressure to bend the juxtaposed flanges outwardly and continuing the application of pressure to flatten the bend against said body member to thereby form a seam attaching the neck to the body member.

2. The'method of attaching a closure element to a container whichv comprises, providing a body member having an opening therein and an upwardly extending annular flange about the periphery of said opening, providing a neck which may serve as a pouring outlet for the container and having an inwardly extending radial flange and an upwardly extending axial flange, positioning the neck over the opening in the body member so that the upwardly extending flange of the neck surrounds and rests against the upwardly extending flange of the body member, exerting pressure to bend the juxtaposed flanges outwardly and continuing the application of pressure to flatten the bend to thereby form a seam attaching the neck to the body member and indenting the seam at a plurality of points to prevent relative movement between the neck and the body member. a

3. In a container, a body member having an opening therein, an upwardly extending neck adapted to serve as a pouring outlet for the 'container, said neck having adjacent its lower end an inwardly extending. annular flange resting upon the body member about the said opening, said flange being crimped back upon itself at its inner edge, said body member having about the said opening an upwardly and then outwardly extending flange crimped over the said neck flange to fasten the neck to the body member.

4. In a container, a body member having an opening therein, an upwardly extending threaded neck adapted to serve as a pouring outlet for the container, said neck having adjacent its lower end an inwardly extending annular flange resting upon the body member about the said opening, said flange being crimped back upon itself at its inner edge, said body member having about the said opening an upwardly and then outwardly extending flange crimped over the said neck flange to form a seam fastening the neck to the body member, a metal seal pressed into the said opening and resting upon said seam, and a metal cap screwed into said neck.
